Introduction
Introduction� In the following years it is expected a huge growth of data traffic in fixed and mobile
access networks
� Fixed broadband access: different ADSL flavors, FTTCurb, FTTH
� Mobile access: 2G, 3G, LTE, LTE-A, WIMAX
6
Introduction
� Fixed & mobile networks have been optimized / evolved independently
� Complete functional & physical separation of fixed access/aggregation and mobile networks
� E.g.: the availability of locations for mobile base station sites and fixed network central offices are not re-considered by each other for future deployments
7
� Challenges
� Cope with the huge capacity demand
� Attain more cost / energy efficient mobile / fixed network infrastructures
� Solution
� Design / deploy scalable Fixed Mobile Convergence (FMC) networks
� FMC idea: to define framework for a common converged network capable of supporting both mobile and fixed services
Scope
� Lot of uncertainty wrt technological evolution due to many technical options in FMC --> COMBO project

Challenges and concept
COMBO Challenges
� COMBO project will answer the key questions addressing FMC challenges:
� Save cost: reduce CAPEX and OPEX ensuring QoE
� Deal with the increasing traffic and changing applications: scalability / flexibility
� Adapt network structure: node consolidation
� Where to locate the intelligence in the network: functions such as handover between cells and technologies, OAM, synchronization, etc.
� Enable multi-operator / multi-vendor environment: interoperability
� Reduce energy: reduce 20% of energy consumption
10
� Joint optimization of fixed and mobile access and aggregation networks
COMBO Concept
11
� COMBO proposes a new access / aggregation network architecture around the innovative concept of NG-POP
� NG-POP disruptive evolution of the Central Office node / local POP
� First aggregation node: mediation between access and core network
� Several constraints: different services and technologies, scalability, operations, ….
COMBO Concept
NG-POP combines two basic aspects of FMC: functional and structural
� Functional convergence (@ or below L3, IP)
� Openness of network interfaces, interoperability among access technologies, unified control plane, better distribution/localization of essential network functionalities (BBUs, P-GW, etc.)
� aim: enhance the QoS, QoE, scalability and flexibility
� Example1: fast handover between technologies (WiFi, WiMax, LTE/LTE-A) and cell sizes (macro, micro, pico, femto)
� Example 2: optimized localization of centralized BBU and P-GW, traffic offloading techniques to efficiently balance traffic load
12
COMBO Concepts
13
COMBO Concept
� Structural convergence
� Mutualisation of fixed and mobile access / aggregation network infrastructures and HW
� Central office consolidation and BBU hotelling techniques
� aim: joint fixed/mobile equipment and infrastructures
� Example 1: convergence of traditional PON access and dedicated wavelengths for mobile traffic backhauling on a single infrastructure with packet over optical aggregation transport segment
14
Aggregation segment: MPLS-TP over WSONAccess segment: PON technologies
15
Targets
� Main target: to deploy FMC networks achieving:
� optimal QoE for the end user
� optimized network infrastructure in terms of increased performance, reduced cost and energy consumption
� Associated objectives:
� Assess multi-operator/vendor FMC scenarios
� Experimental demonstration of FMC features and concepts in lab and field trials
� Drive standardization activities
